Title: TV and telephone link for documents - permits transmission of images and marking joints by light pen with compensation for transit time delay
Inventor: LAMPL JOSEF
IPC: H04N7/14
Filed: 1976-06-25
Abstract: A TV/telephone link permitting the display of documents superimposed on the transmitted images of the two subscribers. Two subscribers (A, B) are connected through an exchange (w); each has a normal telephone instrument (F1, F2), a camera (K1, K2) and a picture display unit (B1, B2). The camera (K1) receives directly the image of the subscriber, and through a mirror the imate of a document to be transmitted, which it converts to a signal to be transmitted to the other subscribers display unit (B2), and vice versa. The receiving subscriber is provided with a light pen (L) so that a specific point on the displayed image can be identified and marked on both display units (B1, B2). Removal of the light pen from its holder activates a number of contacts to activate a pulse transmission circuit which assures compensation for the transit time between subscribers to that the spot displayed to the first (sending) subscriber is identical with that marked on the screen by the receiving subscriber.

Title: Yarn winding sleeve - has circular surface bulges linked by curved webs to retain mechanical stability during yarn heat or fluid treatment
Inventor: ENGEL ADALBERT
IPC: B65H75/24
Filed: 1976-07-15
Abstract: In the mfr. of a textile cylindrical body, made of thermoplastic materials, it is given a regular or a conical shape to support cross-wound yarn or thread for thermal and/or fluid treatment, using a mantle which is axially resilient at least under heat. The mantle has approximately circular bulges or the like, linked by curved webs which, when relaxed, have an axial range greater than the radial height of the bulges over the webs. The increase in the radial cross section, through axial pressure, is sufficiently large to prevent the wound yarn from loosening, while the sleeve body retains its mechanical stability.

Title: Single cell proteins by aerobic fermentation - in serpentine horizontal tubes with integral cooling heat exchanger
Inventor: HAWKINS HAROLD MILLS VERSTORBE
IPC: C12M1/04
Filed: 1976-10-02
Abstract: A fluid is pumped through a serpentine system of generally horizontal tubes provided with an integral heat exchanger. Oxygen is injected at the upstream end of the tube system and fermentation takes place while the resultant heat is removed by the heat exchanger. A vertical tank contg. horizontal trays receives the output from the tubes and allows gas to escape escape from the liq. which is recycled to the tube system. Pref. a foam separating vessel is used to recover liq. prod. from the tank. The appts. is used in the prodn. of single cell protein by the aerobic fermentation of microorganisms using methanol as the feedstock. The use of an integral heat exchanger presents a large surface area to the fermenting liq. for heat removal.

Title: Weft supply mechanism - has a torque limiter with adjustable dampeners to simplify faulty weft rectification
Inventor: SCHEFFEL WALTER
IPC: D03D47/34
Filed: 1977-04-26
Abstract: Where the weft yarn for a loom is held in a supply spool, rollers draw out the yarn and a length is stored by a moving deflector travelling along a guide path. A torque limiter is incorporated in the common drive for the drawing out roller and the deflector. This is composed of a drive output and drive input section, with limit stops for each section to limit the rotary angle between the two sections. Dampeners are located between the sections to act against counter rotation, dependent on the torque in both directions. There is a separate dampening factor which is adjustable for each rotary direction. The system allows faulty wefts to be corrected, without reversing all the loom components.
